【発明の詳細な説明】 （産業上の利用分野） 本発明は、道路に沿つて埋設されるＵ型側溝体
の改良に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to improvements in U-shaped gutter bodies buried along roads.

（従来の技術とその問題点。） 舗装道路の両側には側溝が道路に沿つて敷設さ

設する事によつて行われていた。(Conventional technology and its problems) Gutters are laid along both sides of a paved road to collect rainwater on the road and mountain water running off from surrounding mountains and drain it, preventing flooding of the road. It is designed to be prevented. These ditches were created by first digging a trench along the road, and then burying U-shaped concrete ditches approximately 4m long into the trench.

高になるばかりか不均一となり、工事の質にばら
つきがあつた。(Problems to be Solved by the Invention) On flat roads, the water in the gutter flows slowly, but on slopes, the gutter becomes steep and the flow speed becomes excessive, causing water to overflow. Therefore,
The flow velocity gradient of the side ditch was determined to match the slope of the road, and care was taken to ensure that the flow velocity within the ditch did not become excessive. On the other hand, for flat areas, U-shaped gutter bodies of the same size and with end faces perpendicular to the bottom can be buried in the trenches excavated one after another, but in the case of slopes, the slope is not constant and the flat area Construction could not be carried out in the same way as construction work, and normally construction was to be carried out on site in accordance with the above-mentioned road construction standards. Therefore, gutter construction in mountainous areas with many slopes was not only time consuming and extremely expensive, but also uneven and the quality of the work varied.

（発明の目的） 本発明は、かかる従来例の欠点に鑑みてなされ

体Ａの強度を高めてある。 The U-shaped gutter body A extends from both sides of the bottom part 1 to the side wall 2.
It has a U-shaped cross section with an upward opening and a total length of 2m. (Of course, the dimensions are not limited to this, and may be longer or shorter than this.) In this U-shaped gutter body, the angle θ 1 formed by one end of the side wall 2 with respect to the bottom surface 1 is an acute angle (5° to 15° in this embodiment), and the angle θ 2 formed with the other end side is an obtuse angle (95° to 105° in this embodiment). And the bottom part 1 formed at an obtuse angle
This is an extension part 3 for placing an end on which the end of another U-shaped gutter body A disposed adjacent to the side gutter body A is placed. Here, the end placement extension 3 is placed so that when the end of the adjacent U-shaped gutter A is placed on the end placement extension 3, the upper end surface of the side wall 2 is flush with the end portion 3. The height H 2 of the end of the side wall 2 on the side of the protrusion 3 (that is, the height from the top surface of the bottom surface 1 to the top surface of the side wall 2) is the height from the bottom surface 1 on the opposite side to the top end of the side wall 2 It is constructed to be equal to H 1 . Furthermore, a reinforcing bar 7 knitted into a net shape and bent into a U-shape is inserted inside the U-shaped gutter body A to increase the strength of the U-shaped gutter body A.

が嵌め込まれるようになついる。 The end surface of the U-shaped gutter body A may be a flat surface, but in order to improve the connectivity between adjacent U-shaped gutter bodies A,
In the end surfaces where adjacent U-shaped gutter bodies A touch each other, a filling groove 4 may be recessed along the U-shaped groove on the end surface on the side of the end placement extension part 3. In this case, the filling groove 4 It is possible to prevent the filler 6 from falling off over a long period of time by making the shape triangular in cross section so that the width of the opening from the end surface becomes gradually narrower as it approaches the inner circumferential surface of the U-shaped groove. In the closed U-shaped gutter body A, a step 9 for placing a lid is formed in a step-like manner on the inner surface of the upper end of the side wall 2, and a step 9 for placing a lid is formed in the step 9 for placing a lid.
It becomes like being fitted in.

次に、道路勾配と流速勾配との関係に付いて設

Next, the U-shaped gutter is laid from the bottom of the slope, and as shown in Fig. Place the end of the gutter body A and connect the two. At this time, a step 5 is generated at the connecting portion between the two, and the flow velocity gradient of the side gutter becomes gentler than that of the gutter (road). Here, the road slope is
If the road gradient is steep (10% to 13%), use the short U-shaped gutter body A so that the flow velocity gradient is 6% to 3%; conversely, if the road gradient is gentle (9% to 7%) A long U-shaped side gutter A is used so that the flow velocity gradient is 6% to 4%. In this way, the U-shaped gutter bodies A are sequentially laid in accordance with the slope toward the upstream side.

If the filling groove 4 is recessed, the mortar or rubber filler 6 is filled into the filling groove 4. In this case, since the filling groove 4 has a triangular cross-section with the opening width gradually narrowing as it approaches the inner peripheral surface of the U-shaped groove, the filling material 6 can be prevented from falling off over a long period of time.

る。(Effects of the Invention) The present invention provides a U-shaped gutter body with an upward opening and a U-shaped cross section, in which side walls are erected from both sides of the bottom part, and the angle formed by one end of the side wall with respect to the bottom part is an acute angle. At the same time, the angle formed with the other end side is an obtuse angle, and the end of the obtuse bottom part is extended, and the end of the other U-shaped gutter body disposed adjacently is Since it is an extension part for placing the end of the U-shaped gutter body on the upstream side, the end part of the U-shaped gutter body on the upstream side is placed on the extending part for placing the end part of the lower U-shaped gutter body. Just outside,
It has the advantage of being able to set a predetermined flow velocity gradient and increasing construction efficiency similar to that on flat areas.

う利点もある。 Furthermore, since a filling groove is recessed along the U-shaped groove on the end surface where adjacent U-shaped side gutter bodies touch each other, by filling this filling groove with mortar or rubber-based filler, the adjacent U-shaped side gutter bodies can be recessed. It is possible to improve the connectivity of the side gutter body, and in addition, by making the filling groove have a triangular cross-section, the opening width from the end surface becomes gradually narrower as it approaches the inner peripheral surface of the U-shaped groove. Another advantage is that the filler can be prevented from falling off over a long period of time.

じ、道路の美観を高める事になる。 Incidentally, when a difference in level occurs at the connecting part in the side gutter, the water flowing through the side gutter changes like a small waterfall, which improves the aesthetic appearance of the road.
